grid solution to handle for defining a max number of 3. This will center that extended content div and make it look like its in line with the. a flexbox solution requiring defining the calculation to restrict the number of columns. Step two is to set the left margin of that same container div to -200. In this case, grid layout easily handles the math to distribute the columns vs. An additional advantage is when you don't want auto-flow but instead want to define a set max number of columns per "row". By apply ::before or ::after to an element, you can insert a dynamic element into the DOM before or after the selected elements children. The advantage of grid is inherently equal-width elements if that is desirable. Step 2: Add the overlay element dynamically with ::after Natively, CSS gives us the powerful ::before and ::after elements for adding stylistic content to the page that shouldn't affect markup. However, elements will not inherently be equal-width as well (which may be an advantage depending on type of content, for example navigation links). scrollLeft/scrollTop – width/height of the scrolled out upper part of the element, starting from its upper-left corner.Īll properties are read-only except scrollLeft/scrollTop that make the browser scroll the element if changed.For purely solving for equal height elements, the advantage of flexbox is the default axis immediately enables side-by-side columns, whereas grid needs to be explicitly set.scrollWidth/scrollHeight – the width/height of the content, just like clientWidth/clientHeight, but also include scrolled-out, invisible part of the element.

clientWidth/clientHeight – the width/height of the content including paddings, but without the scrollbar.

For right-to-left OS the vertical scrollbar is on the left so clientLeft includes its width too. For left-to-right OS they are always the widths of left/top borders. The width and height of the span can be set by using the block and inline-block values of the CSS display property.

clientLeft/clientTop – the distances from the upper-left outer corner to the upper-left inner (content + padding) corner.

offsetWidth/offsetHeight – “outer” width/height of an element including borders.

offsetLeft/offsetTop – coordinates relative to the upper-left edge of offsetParent.

offsetParent – is the nearest positioned ancestor or td, th, table, body.

SummaryĮlements have the following geometry properties: Please note that the described difference is only about reading getComputedStyle(.).width from JavaScript, visually everything is correct. But on low-resolution devices, such as computer screens, CSS doesn't require that. On a laser printer, 1cm should be exactly 1 centimeter. That’s because Firefox returns the CSS width and other browsers return the “real” width. The so-called absolute units ( cm, mm, in, pt and pc) mean the same in CSS as everywhere else, but only if your output device has a high enough resolution. But Firefox shows 300px, while Chrome and Edge show less.

On a Desktop Windows OS, Firefox, Chrome, Edge all reserve the space for the scrollbar. The element with text has CSS width:300px. If your browser reserves the space for a scrollbar (most browsers for Windows do), then you can test it below. Such cross-browser differences is the reason not to use getComputedStyle, but rather rely on geometry properties. Firefox) – CSS width (ignore the scrollbar). Chrome) return the real inner width, minus the scrollbar, and some of them (e.g. …But with getComputedStyle(elem).width the situation is different. The outer element is now a rectangle again, since you set a height for it.

And clientWidth/clientHeight take that into account. Save and reload, and youll see some changes. So the real width available for the content is less than CSS width.

Sometimes the code that works fine without a scrollbar becomes buggy with it, because a scrollbar takes the space from the content in some browsers. So here CSS width is useless.Īnd there’s one more reason: a scrollbar. Alert( getComputedStyle(elem).width ) // autoįrom the CSS standpoint, width:auto is perfectly normal, but in JavaScript we need an exact size in px that we can use in calculations.
